This invention relates A. to apparatus for applying a preservative such as tar, pitch, or the like7 to thread, cord, fishing lines, etc.

n The object of Vmy invention is the provision of apparatus of this character which will be of inexpensive construction, and convenient to operate,v aiording structureadapted to obviate the heretofore annoying direct contact with the preservative, the invention y being peculiarly effectiverto itsguse in eX- posed situations in any atmospheric conditions. y

The invention consists in a pot in which the preservative is heated andmaintained at a condition of fluidity suitable for treating an article, a means to cause ythe article to be progressively dipped in the preservative material and eventually wound compactly about a spool from which pieces of the article may be withdrawn tor use. The invention further consists in the novel construction, arrangement and combination ot parts hereinafter described and claimed.

ln the accompanying drawings, Figure 1 is a plan view of apparatus embodying my invention; Fig. 2 is a view partly'in side elevation and partly in longitudinal vertical section of Fig. 1; and Fig. 3 is a detail transverse sectional view through 3 3 ot F ig. 2.

As shown in the drawings the trame of the machine comprises a base 5,*which may be of wood, and serving as a support for standards 6 and 7 located near the opposite ends of the f f base and also :tor the legs 8 of any open vessel or pot 9 located between said standards. Said legs are rigidly secured to the pot about its periphery and have their lower ends turned outwardly to serve as feet 10 through t whichextend screws 11 whereby the pot holding` legs are secured to the base.

The pot 9 issupported at an elevation to accommodate a lamp stove 12 therebelow in which fuel oil is burned to generate heatl to liquety the material, hereinafter termed tar,

5 indicated by 13 in Fig. 2. Y

14 represents a tubular shell of an internal diameter to be placed over and surround the lower portion of the peripheral wall 9 of the pot and to enclose the legs 8 above the respec-V 56 tive feet 10.

Slots or openings 16 are thus provided below the lower edge of the shell for the admission orn air to support combustion ofthe lampV fuel, and outlet openings, as 17, are provided between the legs 8 for the discharge ot smoke and `othergaseous combustion products. 18 represents a handle provided on the shell for raising itto give access tothe stove 12 to light and regulate the same, and also for replenishing the oil. Y

i The standard serves as a holder fora roll 19 about whichis wound the article, such as thread 20,*which is to be tarred. The roll is supported for rotary motion upon a pin 21 which is withdrawable from the standard. f

`he other standards, 7, as shown, consist of two companion members each having a bearing for a fcrank shaft 22 held in place by means `of caps 23 which are secured by removable pins* 2li. 25 represents a reel f mounted upon said shaft to rotate therewith for winding the thread about the reel by turning the V'same by means lot the shafts crank 26, employed as a handle.

Secured to the inner surtacey ot the peripheral wallet the pot at that side nearest the standard 6 is a bracket havingvtwo vertically spaced apertured arms 27 through which eX- tends torvertical movement the shank 28 ot a threadguide. The upper end of the shank above the bracket is formed with an eye produced by bending such shank end spirally, as at 29, permittingthe thread to be entered helically into the eye. i' Below said bracket the shank of the guide is extended as a hori- Zontal arm BO which terminates in a loop 81 to'receive the thread therein. rlhe thread withdrawnfrom the roll is passed or threaded throughboth the eye and loop elements of the guide when the guide, for the purpose, is held by the operator in the elevated position in which it is indicated by dotted lines X in Fig. 2, after being thus threaded the guide is pushed downwardly into the operating position in which itis represented by full lines in the referred to view, whereby the thread in proximity to the loop 31 is caused to be submerged in the tar. The thread is drawn from the roll 19 and through the guide when the thread iswound about the reel 25. A pair litt of pressure blocks 82, preferably of rubber or a composition containing rubber, are employed above the pot, between which blocks the thread is caused to pass after leaving the tar to rid the thread, by squeezing, of excess tar Awhich falls into the pot.

As shown, the blocks 32 are provided within a holder of a frame which is rigidlyK connected as by means egt a bracket 34 to the pot. Said blocks, moreover, are located between an end 35 of said holder and apressure plate which is regulated by means of an adjusting screw 37 operable in a screw threaded hole provided in the other end 88 of the 1 holder.

n operation, the thread wound about the reel Q5 withdraws the thr ad from the roll 19, whence it passes through the guide eye 29 and loop 3l whereby it is dipped in the molten tar contained in the pot, and thence between the resilient blocks 32 which serve to wipe superfluous tar trom the thread. The reel may be removed from the standards 7 after removing the shaft 22 therefrom.

7What l claim is,-

l. The combination, in a. device for tarring thread and the like, of a tar-containing pot7 means to retain the tar in said pot in a state of fluidity, a supply roll mounted for rotation at one side ot the. pot, a reel mounted for rotation at the other side ot the pot, a thread guide freely mounted for vertical movement and adapted to submerge and elevate the thread within and Atrom the tar in the pot, and pressure means disposed between said guide and the reel for removing superfluous tar from the thread, said thread guidev comprising a. rod member coniigured to present a shank terminating in an Ieye at the top an d a. loop at the bottom, the thread being adapted to pass successively through said eye and the loop.

2. In a device for tarring thread and the like, a. tar-containing pot, a bracket disposed at one side of the pot, a thread guide freely mounted for vertical movement in said bracket tor submerging and elevating the thread within and from the tar in the pot, and pressure means carried by said pot at its opposite side and through which the thread is adapted to pass 'for removing superiluous tar from the thread. said thread guide comprising a rod conformed to present a shank slidable in aid bracket and bent at its opposite extremities to respectively present an eye above and a loop below the bracket, the thread beingr successively passed through said eye and the loop,

3. In tarring devices as defined in claim 2, wherein the thread is adapted for insertion and removal from said eye. and loop without detaching the guide from the pot.

In a device for waterproofing thread and the like, a pot for containing' a waterproofing liquid, an apertured bracket disposed at one side of the pot, a thread guide supported for vertical movement in said bracket for submerging and elevating the thread Within and from the liquid in the pot, said thread guide comprising a rod, the shank of which is slidable in the aperture of said bracket and the opposite ends being looped to provide threadreceiving eyes, the upper of said eyes beingr disposed in the approximate vertical axis oi the rod shank and the lower of said eyes being disposed in offset disposition of said axis, the thread being passed successively through the eye above and the eye below the bracket with the offset disposition of the lower eye serving to yieldably retain the rod in its lower-most position to submerge the thread responsive to the binding ot the. sliding shank in the bracket.
